New User Registration

The term “new user” refers to an individual who does not currently have an identity (Single Sign On user ID 

and password, or SSO account) established to access Treasury applications via the UPS or ISIM provisioning 

services. If you already have an SSO account with which you access other Treasury applications via UPS or 

ISIM, proceed to the User Enrollment or Agency Administrator Enrollment section of this guide. 

To create an identity (Single Sign On user ID and password), access the Fiscal Service Self-Enrollment page at 

https://isim.fiscal.treasury.gov/selfenroll/register. When the page opens, enter information in all required 

fields (denoted with an asterisk), retype the validation text in the corresponding field, and then click Submit.

Note: Access to the IPAC Application requires a government email (no .com emails will be accepted). Email addresses will be 

reviewed on an ongoing basis.

7. If selecting the RITSB module option, enter the RITS Payroll ID in the appropriate field of the ALC column 

(if the RITS Payroll ID field is populated, the ALC field below it should not be populated).

8. After all three fields are populated with your selections, click Add. This will add the Module/Role/ALC 

combination to the Current Permissions section.

NOTE: Only one ALC may be selected per row. To add additional modules/roles for the same or other

ALCs, move through steps 6-8 as many times as needed. Upon entering each module/role/ALC 

combination, verify that it appears in its own row under Current Permissions. To add additional access 

at a later time, it will be necessary to follow the instructions in the Account Modification section of this 

guide.

12. When the Request Submitted: Request Account page appears, click View My Requests to view the status 

of the request.

13. When the View My Requests page opens, the status of the request will be visible. To view request details, 

click Account Add to access the Request Information page, including the list of approvers who are 

authorized to take action on the request. When the request has been completed (approved or rejected),

the status will change accordingly.

IMPORTANT NOTE: Access requests are reviewed and approved/rejected on a case-by-case basis according to the ALC selected. 

Each ALC has at least one Agency Administrator (AA) and one Master Administrator (MA) who approve access requests. If multiple 

module/role/ALC combinations are submitted, a separate access request will be sent to the appropriate AA/MA for the ALC from 

each combination, even if the AA(s)/MA(s) are the same for all ALCs to which access was requested. 

Because access to a variety of module/role/ALC combinations may be requested within a single submission, 

it is possible that one of the combinations may have been rejected by the AA and/or MA for that ALC, even if the submission

appears on the View My Requests page with a status of “Success.” If you are unable to access IPAC with any module/role/ALC 

combination(s) you requested, you will need to resubmit an access request for the missing module/role/ALC combination(s) as 

described in the Account Modification section of this guide.

combination into the Current Permissions section.

NOTE: Only one ALC may be selected per row. To enroll as an AA for multiple ALCs, move through steps 6 and 7 as many 

times as needed, selecting a different ALC each time. Upon entering each ALC access request, verify that it appears in its own 

row under Current Permissions. To add AA access for additional ALCs at a later time, it will be necessary to follow the 

instructions in the Account Modification section of this guide.

If you need other IPAC roles outside of the AA designation, you can also select them from this screen by following the steps 

above.

of the request.

click Account Add to access the Request Information page, including the list of approvers who are 

authorized to take action on the request. When the request has been completed (approved or rejected),

the status will change accordingly.

IMPORTANT NOTE: Access requests are reviewed and approved/rejected on a case-by-case basis according to the ALC selected. For 

Agency Administrator (AA) access, each request will be sent to the Master Administrator (MA) for that ALC. If access requests for 

multiple ALCs are submitted, a separate access request will be sent to the appropriate MA for each ALC, even if the MA is the same for 

all ALCs to which access was requested. 

Because access to multiple ALCs may be requested within a single submission, it is possible that a specific ALC access request within 

the submission may have been rejected by the MA for that ALC, even if the submission appears on the View My Requests page with a 

status of “Success.” If you do not receive approval requests for any ALC to which you requested access, verify whether you have the AA 

role for that ALC. If not, you will need to resubmit a request for AA access to that ALC as described in the Account Modification section 

of this guide.
